T0 aZlw/wnc it may concern.-

Be it known that I, JOHN A. STAOKHUUSE, a citizen of the United States, residing at Dover, in the county of Morris and State of New Jersey, have invented a new and useful Grate for Bakers Ovens, of which the follow-v ing is a specification.

This invention relates to grates for stoves, furnaces and similar heating apparatus and more articularly to that class of grates esecial y designed for use in connection with akers ovens.

The object of the invention is to provide a combined tilting and shaking grate the supporting frame of which is positioned in the floor of the oven with the operating handle disposed within convenient reach of the o erator so that the latter may readily trim t 1e fire without the necessity of introducing a poker or similar tool into the oven to accomplish this purpose.

A further object of the invention is to form the grate bars with vertically disposed lugs or projections for agitating the fuel when the grate is oscillated, and furtherto provide one end of the grate with a weight or counter-balance for automatically returning the grate to operative position after the same has been tilted to dumpthe fuel.

A still further object of the invention is to generally improve this class of devices so as to increase their utility, durability and efliciency.

With these and other objectsin view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, and illustrated in the accompanying drawings, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the sco e of the appended claims.

11 the accompanying drawings forming a part of this specification: Figure 1 is a longitudinal sectional view of a bakers oven provided with a grate constructed in accordance with my invention. Fig. 2 is a perspecti ve view of the grate detached showing the parts separated.

Slmilar numerals of reference indicate corresponding parts in all of the figures of the drawings.

The improved grate is princi ally designed for use in connection wit bakers ovens and by way of illustration is shown applied to a bakers oven of the ordinary construction in which 5 designates the oven, 6 the pivoted door and 7 the ash pit.

Arranged at the rear end of the oven in a suitable recess 8 formed in the floor of the latter is an annular supporting frame 9 pro vided with a laterally extending flange 10 which bears against the adjacent wall of the recess 8 and is secured to the floor of the oven in any suitable manner, as by cement or similar lastic material 11.

Pivotal y mounted for tilting movement in the supporting frame 9 is an oscillating grate 12 provided with an angular extension or terminal 13 which projects through an elongated slot or recess 14 formed in the walls of the supporting frame for engagement with the correspondingly squared socket 15 of an operating handle 16. Extending laterally from the opposite sides of the grate 12 are pins or trunnions 17 which engage the adj acent walls of segmental slots 18 formed in the supporting frame, said pins or trunnions being introduced into the slots 18 through vertically disposed recesses 19 communicating with the slots 18 and opening through the top of the frame, as shown. The upper or active faces of the grate bars are formed with vertically disposed lugs or projections 19 'which serve to agitate the fuel when the grate is oscillated and thus effectually trim or clean the fire. weighted, as indicated at 20 so as to counterbalance the grate and automatically return the same to operative position after the latter has been dumped to deposit the burned coals inthe ash pit.

In order to shake or trim the firethe operator opens the door 21 at the rear of the oven and positions the handle 16 on the angular extension 13 after which the handle is reciprocated so as to agitate the fuel and thus precipitate the ashes in the pit 7. In order to dump the grate it' is merely necessary to exert a downwardpressure. on the free end of the operating handle 16 when the fuel will fall into the ash pit, said grate being returned automatically to horizontal or operative position by the counter-balance or weight 20.

Attention is called to the fact that the shoulders 22 formed by the recess 14 serve to limit the lateral movement of the operating lever. In order to rer'nove the grate from the supporting frame it is merely necessary to rotate the same untilthe trunnions or pins 17 register with the vertically disposed slots One end of the grate 12 is the supporting frame, as will be readily understood. By having the grate pivotally mounted for sliding movement in the supporting frame the fire maybe readily cleaned or trimmed Without the necessity of introducing a poker through the oven which is usually done when a rigid or stationary grate is employed.

While the grate is particularly designed for use in connection with bakers ovens it is obvious that the same may be used with equally good results on domestic cooking or heating stoves, furnaces or similar heating apparatus.

Having thus described the invention what is claimed is:

1. A deviceof the class described including a supporting frame having oppositely disposed segmental slots formed therein and intersected by vertical recesses, and a grate provided withlaterally extending trunnions slidably engaging the walls of the slots, said grate being capable of tilting movement on the trunnions.

2. A device of the class described including a supporting frame provided with oppositely disposed slots intersected by vertical recesses and having a segmental opening formed in one wall thereof, an oscillating grate pivotally mounted for sliding movement in the slots and having one end thereof weighted,

and an angular extension formed on the.

grate and projected through the opening in the supporting frame for engagement with an operating handle.

3. The combination with a bakers oven, of a supporting frame secured to and piercing the floor of the oven and provided with oppositely disposed segmental slots intersected by vertical recesses, and an oscillating grate pivotally mounted for sliding movement in the slots and having one end thereof weighted for automatically returning the grate to operative position after the latter has been tilted.

4. The combination with a bakers oven, of a supporting frame secured to the floor of the oven and piercing the latter, said frame being provided with oppositely disposed slots intersected by vertical recesses, an oscillating grate having lateral trunnions slidably mounted within the slots, one end of the grate being weighted and its opposite end provided with an angular extension for engagement with an operating handle, said grate being capable of tilting movement on the trunnions.

5. The combination with a bakers oven having an opening formed in the floor thereof, of a supporting frame provided with a laterally extending flange engaging the walls of the opening and provided with oppositely disposed segmental slots intersected by vertical recesses, said supporting frame being provided with an opening defining stop shoulders, and an oscillating plate having lateral trunnions slidably mounted within the slots, one end of said grate being weighted and the opposite end thereof provided with an angular extension projecting through the opening in the grate for engagement with an operating handle,said grate being capable of tilting movement on the trunnions.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
